61 Evinrude 10022 Rebuild/ wont get to speed at full throttle

[ShaneDeVon]

So i am completely new to working on any boat motor( i am mechanically inclined though), i was given a number of old outboards and decided to try my hand at getting them running. I started with a 61 evinrude 10022 10 hp which was not running although it had good compression on both cylinders.

I want to use this motor on my 10' livingston for fishing in smaller lakes, with that in mind i decided to go through it from the ground up.

I have done
lower unit reseal
water pump replacement
new fuel pump
new fuel lines
carb rebuild
new points, condensors, coils, plugs, and wires
i set the points at a loose .020, then hooked up a multimeter and adjusted each to open right between the timing marks on the flywheel ( i've never dealt with magneto timing so this was a bit of a pain to learn on)

i put it all back together, it starts up first pull, i've got the low speed idle to where it idles great at low rpm.


Now here is my issue, i took it out on the lake for final adjustments to the low and high speed, the low went easy, but when i put it in gear and crank it full throttle the rpms dont kick up as they should no matter how i adjust the high speed needle, it pushes my livingston along at 6 mph at wot. i did set my cam follower and sync it to my carb. I'm at a loss for what i've done wrong or missed. it chugs along no issues dying or anything but the rpms just dont kick up and give it any real speed. i've tried manually opening the butterfly valve all the way and that changes nothing as well.


any help or advice here would be greatly appreciated, i feel like i'm missing something obvious

Do you have spark on both cylinders? What is good compression?

 

[ShaneDeVon]

compression is at 82/85, i have spark in both cylinders. i've tried popping one plug wire off at a time while running and although it runs a bit rough it can continue idling on either cylinder alone. I am planning on checking with an inline plug tester this evening though.

How did you do the pump conversion? Use a tester that measures air gap set it to 1/4".

I'm not sure what you mean by that. If you're referring to converting from one of the old suction tank style 2 hose pumps, this engine was a year or 2 after they stopped using those, so its already a single line.

All I did was unbolt the old pump, swap the gaskets out for new ones and bolt on the new pump, is this where I was supposed to set the air gap? If so would you mind explaining how exactly I do that, because I have no clue :/

 

[ShaneDeVon]

Okay I was doing some research on this, do the new fuel pumps not come with the air gap spring set properly?

 

[flyingscott]

No get a spark tester that you can set the air gap on. Spark must jump a 1/4" gap an inline tester will not tell you that. Your fuel pump is fine that was my fault sorry. Did you clean the carb thoroughly? Have you adjusted the low speed screw to 1.5 turns out? Have you adjusted the high speed jet to the same? Those #s will get you started and you can adjust from there.

I was taught to adjust the high speed needle first . Not sure if correct but has worked for me.
.

 

[flyingscott]

Why would you adjust the high speed needle first? The motor starts on the low speed needle, and if that is adjusted incorrectly it wont even get to the high speed adjustment.

 

[hardwater fisherman]

Just what I read. As I said may be wrong. The motor should start and get up to speed with the slow speed needle set to 1.5 turns.

 

[racerone]

When the motor starts and on a boat , full throttle in gear you adjust the high speed needle first !!----No need to argue that.

Yes there is, If you adjust the low speed to lean it will not even accelerate. Tell us how do you adjust the high speed when that happens. How many times have you told people to adjust the low speed needle to cure a bog or stalling.

No get a spark tester that you can set the air gap on. Spark must jump a 1/4" gap an inline tester will not tell you that. Your fuel pump is fine that was my fault sorry.

I'd already set the gap on the plugs and it jumps a qtr inch just fine. Ive gone through the carb 3x now in the last week and it's spotless. I set the initial low speed at 1.5 turns, high speed around 1 turn. I fine tuned the low speed, my prop empties my metal trashcan too fast to adjust the high speed at home so I'm taking it to the lake today to try it again

Maybe thats my issue, id adjusted the low speed at home first, i can get it to idle very low but it is pretty lean when i do that. I'll try backing it out to 1.5 and adjusting the high speed first today and see what happens

 

[ShaneDeVon]

Okay I took it back out, reset the low and high speed, tried setting low first then high, got it to 7mph, tried high first then low again topped out at 7mph. It just won't pick up the rpm and at higher speed it runs a little rough like its a timing issue.

I had set the timing via a multimeter and alligator clips under the flywheel and set the points to open right between the timing marks on the flywheel... is there a better way to set them? Or to confirm its properly timed?

 

[hardwater fisherman]

I think that if using a multimeter the points should just start to open when reaching the timing marks.. I do know for sure that the points should be at .020 at the high spot of the cam.

 

[racerone]

Using the meter is the best way to set the timing !!------Start motor.----Let it idle.-----Pull one plug lead off at a time.-----What does the motor tell you when you do that test ???
